The first submarine telegraph cable, laid by the
brothers Jacob and John Watkins Brett between England and France in August 1850, was of
simple construction - a copper conductor with gutta percha insulation and no armoring.
It worked for only a day, then broke from chafing on rocks; another version says that the
cable was hooked by a fisherman and destroyed, It quickly became apparent that cables
needed to be armored to withstand not only the stresses of being laid and the risks of
being damaged by fishing vessels, but also the predations of aquatic life.
Concurrent with the development of telegraphy, and
similarly driven by the needs of the Industrial Revolution, wire rope manufacturing had
begun in the 1830s in both Britain and Europe. The impetus for producing a
replacement for the traditional hemp and other fiber ropes came from the mining
industry. Most of Europe's energy was supplied by burning coal, and unlike in the
United States where coal lay near the surface, Europe's coal came from deep mines.
This required moving men and coal through vertical shafts often several thousand feet
deep, and safe operation of heavy loads at these depths was not possible with hemp
ropes.
The first wire ropes were made with iron wire, using the same manufacturing
methods as for hemp rope. By 1834 wire ropes developed by the German engineer
Wilhelm Albert were being used in the mines in Germany's Upper Harz district, and it was
estimated that the additional manufacturing cost was more than covered by the much longer
life of the wire rope over traditional hemp ropes. The new technology spread rapidly
to Britain, and by the late 1830s there were a number of companies making wire rope.
In 1837 Lewis Gordon, formerly an assistant to Brunel during the
construction of the Thames Tunnel, made a career change to practical mining, and entered
the Freiburg School of Mines in Germany, and then the Ecole Polytechnique in Paris.
In 1838 he visited the mines at Clausthal in the Harz mountains, and met Wilhelm
Albert. Impressed by what he saw, he wrote to his friend R.S. Newall in Britain on
June 20th, 1838, urging him to "Invent a machine for making (wire ropes)".
Robert Sterling Newall was born in Dundee, Scotland, in 1812
and in 1838 he was proprietor of an engineering works in that city.
His importance to the telegraph historian will be described
more fully later. On receipt of Gordon's letter, Newall set
to designing a wire rope machine, and by the end of July he had sent
Gordon a drawing of a machine which would produce a wire rope of four
strands and four wires to a strand. On Gordon's return from
Germany in 1839, he formed a partnership with Newall and Charles Liddell
(a former pupil of railway engineer George Stephenson). By August
17th 1840 Newall took out a patent for "certain improvements
in wire rope and the machinery for making such rope", and immediately
following this the three partners established themselves as R.S. Newall
and Company in Dundee, and commenced making wire ropes for "Mining,
Railway, Ships' Rigging, and other purposes".
An important
feature of Newall's wire rope was a central core of hemp or other
flexible material, which ensured that the individual wires and strands
were held equidistant from their respective centers to ensure equal
stress on each wire.
After the Dover to Calais cable failed in August 1850,
a pamphlet written by Robert McCalmont in September of that year refers to Newall and
states:
"He proposes that the gutta percha lines
containing an insulated wire should be surrounded with strong wire rope; that a rope of
gutta percha cords, with their insulated wire wicks, should, in fact, constitute the core
of a strong wire cable, to be laid at the bottom of the sea".
Historians dispute whether
Newall in fact originated this idea of a cable within a wire rope;
Newall himself made a not very definite remark claiming credit in
a letter to the Times of 12th November 1852, but did not make
the claim firmly until he published a
pamphlet on the subject in 1882. Newall states that in September
1850 he submitted a specimen of his cable to the engineer of the Anglo-French
Telegraph Company, on the understanding that Newall and Company were
to get the contract for manufacturing it. The Anglo-French Company,
however, in July 1851 let the contract to Edward Weatherley, who had
made modifications to the wire rope machinery to evade Newall's patent.
Newall obtained an injunction, and forced the Anglo-French Company
to come to him to manufacture the cable, as they were under time constraints
by the terms of their cable-laying concession. Newall and Company
completed the contract by hiring Weatherly's factory and using Newall
employees to produce the cable, which was successfully laid in September
1851. The galvanized iron wire used by Newall to armour the cable was made by Richard Johnson Brothers of Manchester, who also supplied half the armouring wire for the 1857 Atlantic cable.
Their initial success in submarine cable manufacturing
led R.S. Newall and Company to expand this part of their operation to deal with cable
laying as well as manufacture. In 1852 the company made and laid the Holyhead-Howth
and Port Patrick-Donaghadee cables; in 1853 the Dover-Ostend and Firth-of-Forth
cables. In November 1854 during the Crimean war the company filled an urgent order
to supply and lay a cable from Varna to Sebastopol, the "Black Sea Cable".
The cable core was supplied to Newall by the Gutta Percha Company, and Newall delivered
and laid the cable in record time. Curious as to how Newall achieved this almost
immediate delivery, competitors had to wait until the cable had been laid to discover that
only the shore ends were protected inside a cable sheath; the remainder of the wire being
joined in a continuous length and laid in the sea with just the gutta percha insulation to
protect it. Despite this, the cable gave good service for nearly a year.
 We turn now to another key figure in cable manufacturing, George
Elliot. Born in 1815 in Gateshead, the son of a coal miner, Elliot became a mining
engineer and in 1840 a colliery owner. In this capacity he dealt with the wire rope
manufacturer Kuper and Company of Camberwell, London, becoming their sole agent and
manager after their bankruptcy in 1849. He moved the works to Morden Wharf, East
Greenwich (on the River Thames near London), and by 1854 Elliot had become proprietor of
the company (in partnership with Richard Glass), paying off the creditors and the original members of the firm.
The firm was soon renamed Glass, Elliot and Company,
and production was turned over from wire rope to submarine cables. In 1856 the Atlantic Telegraph Company placed
an order for 2500 nautical miles of cable, one half to be made by Glass, Elliot, the other
half by R.S. Newall and Company. This resulted in a famous engineering blunder; one
half of the cable being made with right-hand lay, and the other with left-hand, which
naturally presented a difficulty when the two halves were to be spliced together.
One can envision the armoring slowly unraveling all the way from the splice to the ends of
both cable sections. The situation was saved by the engineers aboard ship, who
devised a complex fixture to ensure that the splice would remain tight. |
The Illustrated Times of August
1st, 1857 describes the fix:
"A rather serious oversight in the manufacture of
the two halves has been cleverly remedied.
"It was not discovered till some time after the
work had begun that the two separate halves had been twisted in opposite directions.
When joined in the centre the natural tendency of this counter formation would have been
to untwist the cable altogether. A very ingenious species of clamp, somewhat akin
to the coupling screws and weights used to connect railway carriages, has been devised to
counteract the natural effects of this blunder".
On July 24th 1857 the Times of London published an article suggesting that the blame for the manufacturing error should be placed with Newall's. Not surprisingly, Newall took exception to this, and sent this letter:
THE ATLANTIC SUBMARINE TELEGRAPH
TO THE EDITOR OF THE TIMES.
Sir,—We have just read in an article in The Times of this day headed "Atlantic Submarine Telegraph" the following paragraph:-
"We have already explained to our readers how the cable is coated with closely woven spiral wires, to prevent damage to the core in paying out; but, in consequence of the two halves having been made at different, places—one at Birkenhead, by Messrs. Newall, and the other at Greenwich, by Glasse and Elliot, a most egregious blunder has been committed. It will scarcely be credited, but it is nevertheless true, that the twist of the spiral wires of the Birkenhead half is in exactly the opposite direction to the twist of the wires in the half made at Greenwich. Thus, when joined in the centre of the Atlantic they will form a right hand and a left hand screw, and the tendency of each will be to assist the other to untwist and expose the core. By attaching a solid weight to the centre joining it is hoped this difficulty and danger may be overcome, but none attempt to conceal that the mistake is much to be regretted. We are informed that Messrs Glasse and Elliot had nearly 100 miles of their portion of the cable completed before Messrs. Newall commenced theirs, and that therefore the fault rests with the firm which began last."
We rely on your sense of fairness to allow this letter a corner in The Times to rebut the charge of our having committed a "most egregious blunder."
1. The conclusion drawn by your correspondent that we are in fault is certainly not warranted. Admitting all the premises, how were we to know anything about Messrs. Glasse and Elliott's work ? We have no entry to their premises, and could know nothing of the lay of the cable they had manufactured.
2. We took our contract from the Atlantic Telegraph Company in December last, and we were supplied by their engineer with a specimen of the cable to be made. We constructed new machinery specially adapted for the manufacture of this cable of the same lay as the specimen supplied to us.
We began to manufacture the last week of February, and when we began about 200 miles had been made at Greenwich. The engineer of the company then found that the lay of the cable at the two works was in reverse directions, and asked us to alter it in ours. We could not do this without altering the machinery which, as before said, had been specially prepared for the work, and this would have involved a delay of three weeks, so that the engineer decided against any alteration. As it has turned out it would certainly have been better to have altered it, for, although we had not begun our half of the cable till the Greenwich firm had completed about 200 miles, yet we had completed our part when they had upwards, of 150 miles still to do, so that there would have been ample time to make the necessary alterations in the machinery without delay in the completion of the cable. However, that was no affair of ours; we were bound to complete, the cable by a certain day under a penalty of 50l. a-day, and we did it; and if the engineer expected the same punctuality from the other contractors we think he was right in not risking delay by alteration of our machinery.
3. The specimen of the cable given to us for our guidance in the manufacture was not made by us, but we believe it was made by Messrs. Glasse and Elliott. At any rate, it is for the engineer to explain how it came to pass that different directions were given to the two contractors; and perhaps the gentleman who gave you the information that we are in fault can throw some light on the subject as to how the specimen given to us happened to be of a contrary lay to the cable manufactured at Greenwich.
The inconvenience arising from the "blunder" is, we think, overrated by you, and really of small importance.
We are, Sir, your obedient servants,
R.S. NEWALL and CO.
24, Abingdon-street, Westminster, July 24. [1857]
The attempt to lay the 1857 cable was not
successful, and the 1858 cable functioned at slow speed for
a short time and soon failed completely. Because of the American
Civil War, and the difficulty of obtaining financing for another cable,
it was not until 1865 that another attempt was made. By this
time Newall and Company were no longer involved in the Atlantic Cable
project, and a merger was made between Glass, Elliot and the Gutta
Percha Company, the new company being known as the Telegraph Construction
and Maintenance Company, or Telcon. The original Glass, Elliot
company continued to make wire rope under the name of George Elliot
and Company for many years.
An engineer who made the transition
in the other direction, from telegraph cables to wire rope, was John
Temple (1839-1922), who worked in the telegraph service in Leeds,
Manchester and London, then joined the Atlantic Telegraph Co. on its
formation in 1856 and sailed on the Agamemnon during the laying of
the 1857 cable. In 1859 he joined Glass, Elliot and Company
and acted as engineer for the Malta, Alexandria, and other Mediterranean
cables. He returned to England in 1865 after the laying of the
cable that year, and was third engineer-in-charge on the Great
Eastern. He also took part in the recovery of the first
piece of the lost 1865 cable with the grappling ship Albany.
He then retired from Telcon, but continued to act as a consultant.
Meanwhile, the firm of Rylands Brothers, wire drawers who supplied
wire for the first Atlantic cable, had taken over the struggling Queen's
Ferry Wire Rope Company Limited, located on the River Dee. At
the suggestion of John Rylands, Temple became managing director of
the company, moving it to Warrington and changing the name to the
Warrington Wire Rope Works Limited. He does not seem to have
had any further involvement in submarine cables after this time.
Both the 1857 and 1858 cables had
been sheathed with cable made from iron wire. For the 1865 and
1866 cables, James Horsfall of the wire rope firm Webster
and Horsfall (Hay Mills, Birmingham) supplied his "Patent
Steel" wire, made by heat treating the steel wire during production.
Steel wire became the standard material used for armoring cable thereafter.
